The brother of an alleged militant leader in Nigeria has collapsed in court just before his trial on charges he took part in an Oct. 1 bomb attack on the country's capital.

Charles Okah, visibly ill, fell to the ground Tuesday before his trial in Abuja, Nigeria's capital. Okah's lawyer, Ogheneovo Otemu, said his client had complained about being ill and had received no medical care while in custody.

A judge later remanded Okah to Abuja's National Hospital and adjourned the trial until Jan. 27.

Okah and three others face terrorism charges over the dual car bombing that struck Abuja during Nigeria's Independence Day celebrations, killing at least 12 people.

Okah's brother, Henry Okah, faces terrorism charges in South Africa over the attack.
